A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. As people get older, they tend to bruise more easily because their blood vessels become more fragile. Watch as Dr. Oz explains more about bruises.
What causes bruising? Impact injuries to soft tissues cause capillaries, small blood vessels under the skin, to break. Red blood cells then leak out of the capillaries and collect under the skin, accounting for the color of the bruise. The color changes in bruises over time signal that healing is in progress and the body is metabolizing the blood cells in the skin. You may bruise more easily as you get older and skin becomes thinner.
